This series add support for SPL to FU540.U-Boot SPL can boot from
L2 LIM (0x0800_0000) and jump to OpenSBI(FW_DYNAMIC firmware) and
U-Boot proper from MMC devices.
How to test this patch:
1) Go to OpenSBI-dir : make PLATFORM=sifive/fu540 O=build_dir I=install_dir
FW_DYNAMIC=y install
2) cp install_dir/platform/sifive/fu540/firmware/fw_dynamic.bin <u-boot-dir>/
3) Change to u-boot-dir
4) make sifive_fu540_defconfig
5) make all
6) ZSBL loads the U-boot SPL(u-boot-spl.bin) from a partition with
GUID type 5B193300-FC78-40CD-8002-E86C45580B47
sudo dd if=spl/u-boot-spl.bin of=/dev/sdc4 bs=1M
7) U-boot SPL expects a u-boot FIT image(u-boot.itb) from 1st
partition(/dev/sdc1)
of SD card irrespective of GUID
sudo dd if=u-boot.itb of=/dev/sdc1 bs=1M
Thanks to Yash Shah <yash.s...@sifive.com> for testing the series.
Changes in v4:
- Split misc DM driver patch into multiple patches
- Added new SPL_CRC7_SUPPORT Kconfig option
- Added DM driver for DDR
- Added clk_enable and clk_disable ops in SiFive PRCI driver
- Added early clock initialization for SPL in SiFive PRCI driver
- Added SPL config options in sifive_fu540_defconfig instead of
creatiing a new config file for SPL
- Update fu540.rst on how to build and flash U-boot SPL
Changes in v3:
